Abstract: Crabs are one of the important economic species in Fujian sea area. Based on the survey data of crabs from January of 2009 to December of 2011, species composition and geographical distribution characteristic of crabs caught by four fisheries in middle and southern part of Fujian coastal waters were analyzed and studied. The results showed that a total of 94 species recorded belongs to 16 families and 53 genera. Most of them are warm water species of subtropical and tropical zones. They are much closer to South China Sea, and a bit far from the Yellow Sea and Bohai Sea. All of these crabs are distributed in shallow sea, while 26.60% of the crabs are distributed both in shallow sea. and the intertidal zone. Most crabs in Fujian sea area are belongs to middle and small-sized species. High-intensity fishing leads to the destruction of the crab resource. So it is necessary to adjust fisheries structure and develop fisheries in open seas. Meanwhile, dynamic monitoring and enhancement and releasing of fishery resource should be carried out, and implementing TAC management system.
